8 Claims. (Cl. 242--157) The present invention relates to a devicefor guidingea.

running strand of yarn and moreparticularly relates .to-

a yarn guide and a support therefor.

The yarn guide and support'of the present invention is particularly adapted for use with various typesofrtex.

Fig. 4. is a plan view showing the manner in which the.

yarnguide is inserted in its support; L

Fig. 5 is a plan view showing the guide inserted in its support; and

Fig. 6 is a plan view of the guide support member.

Referring to the drawing, the guide 10 is an elongated member preferably of rectangular cross section. Guide member 10 has a yarn receiving eye 11 formed therein connecting with a yarn admission passage 12. Guide member 10 has a base or mounting portion 13 provided with opposed notches or grooves 14 and 15 that are formed in its opposite sides extending transversely of its longitudinal axis and adapted to receive elements of the supporting member. The end of guide member 10 adjacent notches 14 and 15 is rounded to provide a convex cam surface 16. Notches l4 and 15 and cam surface 16 are all substantially parallel to one another.

Notch 14 has parallel side walls that extend inwardly and rearwardly of guide member 10 to provide a hook or nose portion 17 adapted to retain a portion of the guide support member, in a manner to be explained more in detail hereinafter, when the guide is being mounted on said support. Notch 15 is relatively shallow and is V- shaped in cross section, the two walls of the V extending inwardly towards each other at substantially the same angle. Guide 10 may be made of any convenient wear resistant material, as for example ceramic material or metal, that will resist wear or cutting from a running strand of yarn.

The guide supporting member 20 is preferably made from resilient wire that is bent to the desired shape. Guide supporting member 20 comprises an upstanding portion 21 having an eye 22 formed on the lower end thereof that is adapted to be engaged by a screw, or some similar securing means, to attach said support to a textile machine. The upper end of the resilient wire is bent to form a resilient guide holding portion. A rearwardly extending V-shaped bend 23, 24 is interposed between upstanding portion 21 and the holding portion. V-shaped bend 23, 24 functions as a deflecting member to guide The yarn, guide.

upwardly moving objects away from guide member 10. and the: guide holding portion. A length 25 extends upwardlyfrom said V-shaped; bend in substantially a continuation; of portion 21. A bend 30 is formedin. the wire. to direct it downwardly and to the rearat approximately a 45 angle to provide downwardly and rearwardlyinclined length 31. degrees to give bend 32 which directs the wire upwardlyand forwardly parallel to length 31 in length 33. Length, 33, terminates in bend 34 that directs. the. wire downwardly substantially parallel to portion 25-and to provide downward length or run 35. Downward run 35 terminates. in the bend 37 that is inclined forwardly. from the plane of lengths 25 and 35 at approximately a. 45 angle to.providetheupstanding stub-or endl38. It will be noted that :upstanding portion 21.is bent slightly. as at i 3940 position the'center of eye 22 substantially in vertical alignment with the yarn receiving eye 11 formed in; guide 10'.

The guide and support of the present invention func surface 16 against vertical portion 25. It will be noted. that notch 14 is spaced from theend, of base 13a distance less than thespacing between the portions 25and 35 0f supportmember 20. so; that rotation of the guide in aclockwisedirection will bring cam:surface 16 into engagement with support-portion.25.. Continued pivoted movement of 'guidemember10 causes cam surface 16' to separatethe parallel lengths 25 and 35 by flexing the parallel lengths 31 and 33 and bend 32. When the guide-has been pivoted to bring, its notches 14 and 15 into the plane of'lengths 25 and.35, the substantially ,verticaLportionZS ofgthe support will snap into-notch' 15 to hold the guide in operative position. To remove guide 10 from the support it is merely necessary to reverse the above procedure. That is to say, guide 10 is grasped and pivoted about length 35 in a counterclockwise direction to snap vertical length 25 out of notch 15.

The upstanding stub or end 38 engages the lower surface of guide 10 and prevents said guide from working downward and out of the securing means. Upstanding stub 38 also functions to insure that guide 10 is properly located relative to the supporting member when it is inserted therein. Inasmuch as said upstanding stud 38 is located forwardly of the plane of lengths 25 and 35,

the lower surface of guide 10 can be positioned on said stub at the time notch 14 is engaged with length 35 thus eliminating any possibility of the guide being improperly located in said support.

Since certain changes may be made in the above product without departing from the scope of the invention herein involved, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

What is claimed is:

1. In a yarn guiding device the combination comprising a guide member having a yarn receiving eye and a base portion, said base portion having opposed notches formed in the sides thereof and extending transversely of the longitudinal axis of said guide member, and a supporting member for said guide member formed of resilient Wire and including an upwardly extending length, a downwardly extending length spaced from and substantially parallel to said upwardly extending length, said two lengths being seated in said notches, and a reverse bend formed on the lower end of said downwardly extending length to provide an upstanding stub having its end in engagement with the bottom of said guide member.
